Okay, I felled a black oak tree in my field last week. The tree was dying so I'm making firewood out of it. I started sawing up the log and everything was going fine until I got about halfway done. My Stihl 290 MS died like it ran out of gas. I filled it up and choked it. It started but when I switched the choke off, it died. Tried 4 or 5 more times and can't keep it running. Checked the air filter and it was pretty dirty so I put a new one in. It's still doing the same thing. Any suggestions?
Thanks.
